Abstract
A signaling unit of a display terminal establishes communication with a content server, video communication terminal, and PC server through a communication unit, and transmits/receives image data compressed by MPEG2, MPEG4, and JPEG. A media control unit switches compression schemes for decoding in a media processing unit on the basis of the received image data. The media processing unit performs decoding processing including inverse orthogonal transformation processing and dequantization processing in accordance with the switched compression scheme. At this time, a single processing circuit performs inverse orthogonal transformation processing and dequantization processing.
